Samsung has sent out invitations to its Unpacked event in September

It’s time for another Unpacked. Samsung sent out invitations Tuesday for an event on September 3 ahead of the IFA electronics show in Berlin. During simultaneous events in Beijing, Berlin, and New York, the company likely will show off the Galaxy Note 4 phablet — its phone-tablet hybrid that spawned a new category of smartphones — as well as other devices such as wearables. Samsung has tended to hold two Unpacked events each year — one early in the year for the latest Galaxy S smartphone and another in the fall for its newest Note device. It unveiled the Galaxy S5 in conjunction with Mobile World Congress in February and introduced the Note 3 phablet at IFA last year. The launches give Samsung the chance to show off its latest hardware and software features, and they generate the kind of attention that only companies like Apple have typically inspired. The latest Unpacked comes as Samsung faces tough times in the key mobile market. Makers of low-cost handsets are threatening its position in regions such as China, and fewer people are buying pricey, high-end smartphones. Tablet sales also have sputtered as consumers wait longer before upgrading to newer devices and as many opt for larger smartphones over smaller tablets. Samsung is counting on its new devices to attract buyers and improve its results.
